To a certain extent, no. The errors should not impact on google rankings. Some of the errors you will have in w3c simply cannot be fixed. For example, I always have issues with validation after adding in facebook like buttons, as well as some advertisment code -> and so long as the page displays ok, then I do not need to worry too much about perfect validation. Another common thing that throws off validation is mixing different codes together. Like <br> and <br /> Code (markup): One is from html, the other is xhtml. But BOTH display correctly, but if you are using the wrong one for the wrong document type (and it is common to see them mixed together on some sites) it might throw alot of validation errors, but while you should fix them, it is not critically urgent. matt cutts discussing html errors and impact on seo matt cutts re-discusses html errors and impact on seo IMO, fix the core templates as best as you can, and you will be fine.
Nice resource @Matt , i hope this videos will help me to fix my sites errors , i tried to fix many times to fix w3 validation , but i failed , now i have to try again . Thanks
